## Gaps

- Ofcom leaves this figure blank for the Isles of Scilly. Its other 4G figures there add up to 100% without it, so no homes or businesses get 4G from all four networks: 1 (Isles of Scilly)

## Caveats

- This counts homes and businesses with a predicted outdoor 4G signal from all four networks. A place with coverage from some networks but not all counts as not covered here. Coverage from at least one network is higher.
- The networks predict their own coverage and keep updating their predictions. It is not measured on the ground, so signal can be worse than the map suggests.
- Outdoor means a signal outside the building. Indoor coverage is lower.
- Ofcom counts a premises as covered when the predicted outdoor 4G signal is at least -105 dBm.
- It covers all premises, homes and businesses together. The figure is a snapshot as at 1 January 2026, and Ofcom publishes a new one twice a year.
- Ofcom publishes percentages to two decimal places, so 100% means at least 99.995%.
- Ofcom publishes no figure for the Isles of Scilly.

## Example: Hackney

In Hackney, 100.0% of homes and businesses had outdoor 4G coverage from all four mobile networks in January 2026.
For the UK as a whole, the figure was 99.2%.
